Advanced Materials series: Using metamaterials to make versatile sensors

Metamaterials are artificially structured materials, engineered to manipulate sound, light and other physical phenomena. Metamaterials present many potential applications from antennas to solar panels, with some being more developed than others.

Metamaterials are made from the assembly of multiple composite elements such as metals and plastics. Metamaterials are purposefully designed to be able to control electromagnetic (EM) waves through blocking, absorbing, enhancing or bending waves. This unique ability arises not from the properties of the constituent materials but from the specific, geometrical arrangement of these subunits, at scales much smaller than the wavelength they wish to manipulate.
